Title
Modifying Microsoft Exchange-specific attributes without Microsoft Exchange in the environment -
Description
Some environments may wish have Microsoft Exchange attributes present on objects and manipulate them locally, with changes being replicated externally via a synchronization agent (DirSync, AAD Connect, etc). In that effort, either all Microsoft Exchange servers are removed and the schema extension is retained, or only the Microsoft Exchange schema extension is installed.
-
Cause
Active Roles is not designed to update Microsoft Exchange-specific attributes, such as mailNickname, without using Microsoft Exchange cmdlets. These need to be processed by an on-prem Microsoft Exchange server. -
Resolution
This is an unsupported configuration. Active Roles requires a local Microsoft Exchange server in order to change Microsoft Exchange attributes on on-prem objects.
